Simultaneous estimation of seed-fertilizer adoption decisions: An application to hybrid maize in Malawi uri icon

abstract

  • Simultaneous models are often appropriate for estimating high-yielding variety (HYV) adoption, but most empirical investigations have been based on single-equation models. Using the econometric application of a model for hybrid maize adoption in Malawi as an illustration, this paper argues that researchers investigating HYV innovations need to consider methods for estimating simultaneous censored systems. Further work with associated estimation procedures and diagnostic tests is needed to improve the measurement and prediction of seed-fertilizer adoption.
